What is the simplified inverse of f(x)=1/(1-x)?

Question

Actually, I've been doing and understanding my homework for a few hours, I just need help with a few problems because I keep getting the wrong answer. Why don't you stop talking to me if you are not going to help me.

Answer 1

Oh please, no need to be so rude about it, Katie. For your information, this is called Yahoo answers for one reason: To provide answers, not to complain about the person in need of help!

Now, as for you, my darling, here is the solution:

I shall replace the f(x) wih y, to make it less complicated for me!

Now change the x for a y and vice-versa

x = 1/(1-y)

Then :

(1-y)x=1

x-yx = 1

x= 1 + yx

x-1= yx

x-1/x = y

TADAH f(x) = x-1/x
